ELECTRIC-LAMP-SOCKET ATTACHMENT.

Specification of Letters Patent.

Application filed Decemberl, 1911.

Patented July 9, 1912. serial No. 665,986.

To all 'whom t may concern:

Be it known that I, IVILLIAM HAAs, a citizen cf the United States of America, residing in the Vborough of Manhattan, in the city, county, and State lof New York, have 1nvented a certain new and Improved Electric-Lamp-Socket Attachment, of which the following is a specification.

The present invention relates to an attachment for operating electric lamp socket switches, and particularly to a device of this character adapted to be carried by a standard electric lamp socket of the thin key or pull chain type, the Vobject of lny invention eing to provide an inexpensive and eilicient'attachment which will enable the operator to actuate the socket switch mechanisrn without inconvenience from or interference with the usual reflector or globe surrounding the lamp bulb.

In the accompanying drawings, Figurey 1 is a side elevation of an electric pull socket, having my attachment applied thereto in one form; Fig.- 2 is a plan View of a portion of the attachment; Fig. 3 is a side elevation of a modified form of the attachmentgFig. 4 is an end view of this form of attachment; Fig. 5 is a plan of portion of the supporting bar; Figs. 6, 7, 8, 9 and 10 are side elevations of details.

In the form shown in Fig. 1, my improved attachment is mounted upon a pull socket 15, which carries a reiiector or shade 16 Vat its lamp-receiving end. The socket chain 17 under ordinary circumstances, lies against the upper portion of the shade, With its loose end to the shade through variato cause injury t1ons in temperature and other causes.

.i operate this pull chain,I provide an arm 18, preferably of bent sheet metal and open 17, while the other arm, ,its outer end the pull cord 27 which hangs 4at one end to form a ring 19, which embraces the socket shell and is clamped thereto by the screw 2O passing through both portions .of the bent metal strip which forms the arm.

down clear of the shade 16, and within-easy dangling over the edge of thelatter. This is not only unsightly, but is apt post 22, at the reach of the operator. A coil spring 28 is carried by the post, one to the pin .29, while the other end is secured to the bell crank lever 24. Upon pulling down t-he arm 26 of the bell crank lever by the pull cord 27, the arm 25 is swung through an arc of sufficient length to operate the switch mechanism control-led by the chain 17, and the'lamp circuit `is thereby i switched on or olil in the customary manner.

The extent of oscillation of the arm 25 is limited by the pin 29, which acts as a stop against which the shoulders 30 on the bell crank lever impinge. While the usual switch mechanism within the socket contains a return spring, the latter is normally of suflicient strength only to properly handle the customary short length of chain 17. Consequently the additional eort put upon this'spring to oscillate a lever 'and pull cord would ordinarily either render the spring inoperative or cause the spring to rapidly deteriorate and p worthless. The function of the spring 29, therefore, -is to relieve the socket switch spring from the additonal Aweight of the lever 24, and pull cord 27, serving in and of itself to return these to their normal posi'- tion, in position :tor a new 'actuation of the switch mechanism, as illustrated in Figl.

In some cases, a key socket is preferred to a pull socket, and for this reason I have shown my invention in a modified form adapted to actuate the usual switch key 3l, Fig. v3. In this case, I provide a rod 32 with forked end 39 adapted at one end to embrace the thumb key 31, while the opposite end passes through the post 22, and carries a four-tooth ratchet 33. Oscillating on this rod 32, I mount the pull-lever 34 on which is pivoted at 35, a pawl 36, which engages the ratchet 33 and is pressed into contact therewith by the pawl spring 37 mounted on the arm 38. The spring 28 is secured, in the same manner as in Fig. 1, to the pin 29 at one end and to the oscillating lever 34 at the other end and serves t0 return the same to initial operating position, while the shouldersl 30 limit the extent of oscillation of the lever in both directions.

The chief advantage of theipresent conend being fastened render the A mechanism struction over devices of the prior art d e.

si ned for like utility lies o the supplemental sprin up 4the weigh in the provision 2,8. which takes t of the4 'osci lating leverancipull cord 27.` But it may .be i yointed out also that the prior art devices, or the purpose of minimizing the additional effort which theyimpose upon the socket switch spring, have been made so light'asto'be flimsy and mechanically unsuited for their purpose. By the provision of the supplemental spring 28 which 'relievesthe socketv switch spring of any unusual work, it is possible to make the arm 18 and its related.'

parts of suiiicient strength to afford -a rigid support mechanically tted to the function- Whichit is intended to perform.

I claim as my invention 1. An attachment for electric lamp sockets comprising'a supporting arm, means for securingl the same at one end to the lamp socket, a post secured at the other end of said arm, an oscillating lever pivoted on said, 20 post, an'd means moving with said arm one direction for engaging and operating l the .socket switch actuating means, together with a spring controlling the position of said lever.

2. `switch operating attachment for electrlc lamp sockets provided with shades,

- comprising an independent horizontal supi 'porting arm, readily mounted on the.socket shell, an upright at thev outer end of said arm, said upright being transversely per# forated to receive either the axis ofan oscillating rock lever, or the end of a rotary connecting arm, together with an actuating lever carried by said upright and a return spring engaging said lever, for the purpose described.
